Via McKinsey, a look at the 31 African cities projected to exceed 5m people by 2040:

According to a recent McKinsey report, by 2040, there will be 31 cities in Africa with populations in excess of five million. Over the next 20 years, more than 500 million people are expected to move to African cities, making it the continent with the largest urban population globally.

By 2040, the continent will feature 12 metropolises each with populations exceeding ten million, as ten more cities join the ranks of Cairo and Lagos. Furthermore, there will be 19 cities with populations ranging from five to ten million, indicating an increase of nine such cities from today’s numbers.

These 31 large cities will be dispersed throughout the continent. Over the past decade, 24 of these locations experienced a GDP growth rate that outpaced their respective countries’ overall growth. When calculated as a weighted average, the GDP of these 31 cities grew by 4% compared to their national averages of 3.2% and the continent-wide average of 3.3% over the same period.
